U.S. Rep. Richard Neal, D-Springfield, and U.S. Rep. Jim McGovern, D-Worcester, have opened large leads in the two western Massachusetts congressional districts Democratic primaries.

With no Republicans running, both are likely headed back to Congress, representing new districts.

Neal, currently the 2nd District representative, leads two challengers from Berkshire County – Berkshire Middle District Register of Deeds Andrea Nuciforo Jr. of Pittsfield and writer Bill Shein of Alford – in the new 1st Congressional District Democratic primary. With 150 of 277 precincts reporting, Neal had 22,250 votes, or 71 percent, to Nuciforo's 6,594 votes (21 percent) and Shein's 2,510 votes (8 percent).

In his hometown of Springfield, where results were complete, Neal carried 83 percent of the vote.

In the new 2nd Congressional District Democratic primary, McGovern, now the 3rd District representative, has an overwhelming lead over challenger William Feegbeh. With 70 of 235 precincts reporting, McGovern led 6,281 votes to 637, or 91 percent to 9 percent.
